View Full Version : 'Movie Offset Seconds' - what are the risks of using 0?

I'm ripping some material where dialogue starts immediately (well, perhaps 50-100ms after) with the ripped VOBs. I've always been a well-behaved DVD2SVCD user and gone with the standard 2 seconds of 'movie offset' for bbmpeg. However, as you can see in this situation it causes a problem, because the first sentence spoken in the rip will be cut off with several words. This makes me want to cut down the offset value to 0 seconds, but I'm not sure what will happen if I do this.

Is the problem that the offset is supposed to cure something that is only player dependant or is it also material dependant? Could I in some way check if it's necessary with this material?

Could someone tell me a little more about the theory behind this problem in general?

I am interested in something that will not work only on my own player, but is at least *likely* to work without sync problems on most players. I am using DVD2SVCD 1.1.0b1c, only one audio track (224 kbps), no subtitles, tmpgenc encoding, no image creation (lots of small clips I image with VCDEasy afterwards).

Thanks for any help!

It wouldn't be there if sync wasn't a problem with some players. Why don't you just try it and see if it causes issues with your player. It doesn't with mine either way. It also doesn't cut off anything from the movie or at least I have never noticed it.

Not sure on this BUT:
I don't think the offset takes something away. My CH402 takes that time away, but on the PC the very beginning is audible when skipping back (buffer). It wouldn't if you were right, would it? Try 10 seconds, see if it gets worse.
